Abstract:

THE DEVELOPMENT OF AN INTERFEROMETRIC SURFACE PROFILOMETER IS PLANNED. KEY PHASE I PERFORMANCE SPECIFICATIONS INCLUDE PRECISION AND RESOLUTION FOR STEEP ASPHERIC SURFACES OF 2.5NM IN SURFACE HEIGHT MEASUREMENT, A SPATIAL RESOLUTION OF 0.2MM, AND THE ABILITY TO HANDLE SURFACE SLOPES IN THE RANGE 25 DEGREES WITH A LINEAR TRADE-OFF BETWEEN THESE TWO PARAMETERS. DURING PHASEII IT IS ANTICIPATED THAT PERISCOPIC OPTICS WILL BE DEVELOPED (TO INSPECT THE INTERIOR OF CYLINDRICAL SURFACES) AND THAT IMPROVEMENTS IN SPATIAL RESOLUTION MAY BE ACHIEVED. THE PROPOSED INSTRUMENT IS BASED ON THE USE OF A TWO-FREQUENCY HENE LASER, AND IS AN EVOLUTION FROM A BREADBOARD INSTRUMENT THAT HAS EXHIBITED SUBNANOMETER HEIGHTRESOLUTION AND 2 MICRON SPATIAL RESOLUTION.
